Kim finished the second day of stroke play with a 36-hole total of 133 at Indian Hills Country Club.
Kims 62 is the lowest 18-hole score in any championship in the history of the USGA. Helen Alfredsson shot 63 in the first round of the 1994 Womens Open. Johnny Miller shot 63 in the final round of the 1973 U.S. Open; Jack Nicklaus and Tom Weiskopf equaled the feat in the first round of the 1980 U.S. Open; and Jim Wilson carded a 63 in the first round of stroke play in the 2000 U.S. Mid-Amateur.
Kim shot nine of 29-33 and made eight birdies. She made three straight birdies on two separate occasions: Nos. 2, 3, 4 and 6, 7, 8.
Her 6-under-par 29, with just 12 putts, tied a USGA mark for lowest nine hole score in a USGA championship with Neal Lancaster, who accomplished that feat in the second round of the 1995 and 1996 U.S. Opens, and Mark Boyajian (1986 Mid-Amateur, first round) and Bert Atkinson (1997 Mid-Amateur, second round).
Aree Wongluekiet, 15, of Bradenton, Fla., who won the Championship in 1999, shot a 1-over-par 71 for a two-day total of 2-under 138, five strokes behind Kim. The only other player under par was Nicole Perrot, 17, of Chile, who shot a 4-under 66 following her opening round of 73 for a 1-under total of 139.
Naree Wongluekiet, older identical twin sister of Aree, withdrew after nine holes of her second round because of a shoulder injury. She was 7-over-par for her round at the time.
Two rounds of match play will be played Wednesday and Thursday. The semifinals are scheduled for Friday morning and the championship final is at 9 a.m. Saturday.
